Review on 🔌 SI-1 Cable Stacker by 3M(TM) - Pack of 25 by Doug Small

These stackers are "regular" but I prefer the red cord stackers from the big stores that have a screw AND nail to hold the stacker in place (the I throw away the supplied screws bundled with these staplers, use #10 self-tapping screws and fasten with a cordless screwdriver). The red jobbies have a "locking" mechanism that keeps your cables in place on the stacker, which I liked better than the "notches" on the 3M stackers. Essentially, the red stackers are "safer in your frame" and the cables inserted into the red stackers are "safer in the stacker".
